Course: Biology

Purpose of Unit

The purpose of this unit is for students to gain an understanding of how genes and the study of genetics has advanced the science of Biology. Students will begin the unit learning about the history of early genetics and prior theories that led to the modern understanding we have today. They will become knowledgable on the significance of genetics as a part of life and how our current knowledge differs from that of the past. Students will be expected to review the topics of meiosis as well as become comfortable with gene vocabulary. Students will complete a dice lab that simulates the odds of a certain feature appearing on the offspring of parents. Students will learn how to complete Punnett squares, starting with monohybrid and moving to dihybrid crosses. Closing the unit will be gene mutations, genetic disorders, and the affects of natural selection on the gene pool.

Grade Span Expectations and Science Practices

Lesson Sequence


Assessment Plan

I will be assessing my students understanding of the topic throughout the unit by conducting two quizzes as well as one unit test that will cover all major topics. The quizzes will be assigned according to lesson completion. The first quiz will take place during the first portion of lesson 4. This will cover the history, vocabulary and the basic ideas of inheritance in how it relates to meiosis. The second quiz will be focused on the students ability to successfully complete Punnett squares, as well as being able to interpret the results. At the completion of the Unit, students will be assessed on the content from the first two quizzes as well as information including gene change and mutation, genetic disorders, and how natural selection affects the gene pool.
Apart from the quizzes, students will be formatively assessed through the completion of exit slips, worksheets, and the Phenotype/Genotype Lab.

Rationale

I have been attempting to make the topic meaningful to students by asking for their input every day at the end of class as an exit pass. If we are to discuss one thing in genetics that is interesting to them a day, I believe that it can make a huge difference in their interest level. I also incorporated a few hands on activities so that students can better understand Punnett squares and inheritance. I assessed student learning from many different angles. Students were asked to complete exit slips for the end of class, take quizzes and a unit test, as well as complete worksheets. Students also completed two hands on labs.
